As is often the case, Krauthammer sees the the big picture:

The Iraq war will end, as will the Bush presidency. But the larger conflict that defines our times — war on Islamic radicalism, more politely known as the war on terrorism — will continue, as the just-foiled London airliner plot unmistakably reminds us. And the reflexive antiwar sentiments underlying Ned Lamont's victory in Connecticut will prove disastrous for the Democrats in the long run — the long run beginning as early as November '08.

Absolutely. The Republicans have dug themselves quite a hole, and the Democrats could make gains this November, but the fight against terrorism is the defining struggle of our time, and Democrats are doomed in the long term given that they have been overtaken by peaceniks.
